About this file
This file is a Request for Information (RFI) Responses document addressing technical and clarifications questions submitted by prospective contractors for two design-build construction projects at Misawa Air Base, Japan.
The two projects involve constructing membrane storage shelters: Site C-1 with estimated ROM of $1,000,000–$5,000,000 and Site A-1 with estimated ROM of $3,000,000–$7,000,000. Site C-1 requires two identical 10m × 15m flow-through membrane structures (clear interior dimensions) with 6.0m × 5.0m open-ended openings, a 4,000-gallon aboveground storage tank (AST) pad with secondary containment, paved staging areas, two manually operated 9-meter swing gates, utilities, drainage systems, and associated site infrastructure. Site A-1 requires four identical climate-controlled warehouses (450 m² interior, 10m × 15m clear dimensions, 7.0–9.0m eave height minimum) with 60% relative humidity and above 40°F controls, mechanical ventilation, electrical service (150 kVA transformer serving all four buildings), drainage, fencing, utilities, and site development. Both sites require geotechnical investigations within 21 days of award, topographic surveys, utility locating and verification (contractor responsibility), and compliance with Japanese and U.S. military standards including UFC criteria and Misawa AB Installation Facilities Standards. Key clarifications include: Site C-1's demolished building is no longer in scope; structure standardization is permitted and encouraged; membrane materials must meet MLIT fire standards with minimum 20-year service life and 10-year warranty; concrete flatwork requires 5,000 psi strength; Site A-1 permits flexible design with standardized identical structures and common electrical service; contractor has design flexibility on layout modifications subject to government approval; no dedicated mechanical cooling required for Site C-1; and transformer capacity may exceed 100–150 kVA if load calculations justify it. The proposal submission deadline is 11 September 2026 at 12:00 PM JST, with potential separate or combined awards based on best value to the government.

Misawa C1-A1 RFIs
| Project | Reference (Sect/Para/Page) | RFI | Government Response |
| Misawa Combined Projects | - | Contract vehicle. The schedule tables at SOW paragraph 17 refer throughout to award of a Task Order. Please confirm whether these requirements will be awarded under an existing multiple-award construction contract, and if so, identify the vehicle. | This will be a standalone contract. We apologize for the confusion. We intended to remove any conflicting verbiage from previous or related contracts and seemed to have missed a good bit. |
| - | Award structure. Will the two projects be solicited and awarded together or separately, and may an offeror propose on one without the other? | Offerors may propose on one or both projects. There will be a possibility of a combined award, but only if that offerors proposal represents the best value to the government for each respective project. | |
| Drawing conflicts. | The Site C-1 drawing set carries NAF Atsugi content throughout, including project number "NFATSU------", a struck-through "Site A2" title, finishes keyed to NAF Atsugi base design standards rather than the Misawa AFB IFS required by SOW paragraph 15.e.7, and general notes directing the contractor to notify NAF Atsugi. The sheet index also indicates 8 sheets where 7 were issued. Separately, the Site A1 drawings still carry the superseded title "Construct Emergency PWM Storage," project number QKKA26-XXXX, and the prior 465 SM footprint against the 450 SM now stated in the SOW. Please confirm which documents govern for bid purposes and whether corrected sets will accompany the RFP. | - "NAF Atsugi" references are typos, this should refer to "PROJECT NO. QKKA26-1043" |
- Site A2 reference is a typo, should refer to C1.
- Working standards should be in accordance Misawa AFB IFS.
-Notes directing contractor to notify NAF Atsugi are typos. Contractor shall notify to 35 CES operations personnel.
- 7 sheets are provided for Site C-1.
- Project number and title are as follows: PROJECT NO. QKKA261109 - CONSTRUCT EMERGENCY PWM STORAGE (SITE A1)
- The footprint for each membrane structure is 450 SM.
-Official RFP will contain the most up to date SOW, but may not contain total clerical corrections to drawings. The RFI responses should take precedence over any conflicting information.
| Misawa Combined Projects | Subsurface information. SOW paragraph 7 | Places the geotechnical investigation entirely with the contractor, due within 21 days of award. Please advise whether any prior borings, groundwater data, or fill history exist for either site, and what lead time should be expected for 35 CES utility clearances and digging permits. | There are no boring, groundwater data, or other historical documents available for these sites. 35 CES utility clearances and digging permits: coordinated through a AF103 and would take 15-20 days for coordination. |
| Site A1 climate control. | The revised SOW replaced the previous mechanical specification with a performance requirement of at least 40 degrees Fahrenheit and no more than 60 percent relative humidity year-round. Please confirm this is intentional, that no mechanical cooling is required, and provide the design outdoor conditions to be used for Misawa. | The SOW change is intentional. Humidity and climate controls are set to ≤60% RH and above 40°F for Misawa. No dedicated mechanical cooling is required. Any system or method may be used to maintain those conditions as long as it has enough capacity for the correctly sized transformer. | |
| Site A1 electrical service. Paragraph 15.k | Specifies a 100 KVA transformer while also directing the contractor to size the equipment. Please confirm whether 100 KVA is a fixed requirement or a planning figure, and confirm the intended point of connection and its available capacity. | 100 kVA is not a fixed size; the contractor will determine the required transformer capacity based on the climate‑control equipment used to maintain conditions above freezing and at or below 60% RH. The point of connection and available capacity should be verified to ensure the selected equipment can be supported. | |
| Misawa Combined Projects | Site C-1 demolition. | The SOW describes only "a small abandoned building (no larger than 500 cubic meters)." Please provide its dimensions and construction type, and advise whether an asbestos and lead-based paint survey has been performed. | The existing building demolition is no longer required and the note on drawing sheet C-200 will be revised. The Contractor is permitted to propose modifications to the physical locations of the flow-through structures and the Aboveground Storage Tank (AST) secondary containment system within the proposed site layout to avoid this building demolition. Any such adjustments are subject to formal review and written approval by the Government prior to the initiation. |
The Contractor must submit a revised Site Layout Plan demonstrating that the relocated structures:
Maintain optimal operational traffic flow for R-11 refuelers and support vehicles.
Comply fully with all applicable Unified Facilities Criteria (UFC), environmental regulations, and SPCC secondary containment capacity requirements.
Do not interfere with existing utility corridors or secure perimeter setbacks.
| Site C-1 sewer manhole relocation. | Please provide depth, invert elevations, pipe sizes, and what the line serves, together with any bypass or outage requirements. | Existing underground utilities including but not limited to pipes, cables, and duct lines are shown on the contract drawings for informational purposes only. This utility data was compiled from the best available historical records; however, the Government does not guarantee the accuracy, completeness, or routing of these subsurface lines, nor does it verify the connections shown. The Contractor shall bear sole responsibility for identifying, verifying, and locating all active and abandoned underground utilities prior to commencing any excavation or site-disturbance activities. To ensure site safety and prevent operational disruptions, the Contractor must: Conduct physical utility locating (including non-destructive methods such as ground-penetrating radar, electromagnetic locating, or potholing) to confirm the exact location, depth, and alignment of all subsurface assets.Clearly mark verified utility corridors in the field and implement comprehensive protection measures to prevent damage during construction. Coordinate with 35th CES and local utility locators to obtain all necessary dig permits. | |
| Misawa Site C-1 | Can the Government provide the drawings in native AutoCAD format, together with all available GIS files, utility drawings, and existing as-built information | There are no boring, groundwater data, or other historical documents available for this site. The Government can provide AutoCAD files of the concept plans that were submitted for the bid. | |
| Can both membrane structures be designed with identical dimensions, layouts, structural systems, electrical systems, and equipment to simplify fabrication, operation, and maintenance? | The Government confirms that both membrane structures may be designed with identical dimensions, layouts, structural systems, electrical systems, and equipment. Standardizing the two structures is acceptable and encouraged, as it simplifies fabrication, reduces design complexity, streamlines installation, and supports consistent long‑term operation and maintenance. | ||
| Can the Government confirm whether any deviations from the concept layout shown in the drawings are acceptable if they improve constructability while maintaining all functional requirements? | The Government confirms that deviations from the concept layout shown in the drawings may be acceptable when they improve constructability and still meet all functional and performance requirements. Any proposed deviation must be submitted for Government review and approval prior to implementation to ensure compliance with the project’s intended operational, structural, and environmental criteria. | ||
| If the existing 2 (two) posts on site – Antenna and Giant voice speaker will stay on the same location as now, is contractor required to install bollard around them and if so, will 4 per post be sufficient | The Government confirms that the existing antenna post and Giant Voice speaker post will remain in their current locations. The Government finds that four bollards per post are sufficient and does not require the contractor to install additional bollards at this time. Any future changes or protective measures would require Government review and approval prior to implementation. | ||
| Misawa Site C-1 | If the existing 2 (two) posts on site – Antenna and Giant voice speaker will stay on the same location as now can the contractor recommend new layout of the shelters or will the government do that? | The Government confirms that the layout shown in the drawings is a concept design. The existing antenna post and Giant Voice speaker post will remain in place, and the Government does not intend to relocate or remove either device.The contractor may recommend a revised shelter layout, provided the design is developed around the existing posts and maintains all functional and performance requirements. Any proposed layout modification must be submitted for Government review and approval prior to proceeding. | |
| Does the site require any cameras or light fixtures excluding the ones on the shelters? | Cameras are not required. For Site lighting, eight (8) metal halide, 400 watt, aluminum pole, 20' high are required. | ||
| Paragraph 2.b in SoW calls for humidity control. How can this be achived if the shelter will not be closed – no roll up doors but will be opened on the sides. | The Government clarifies that this site is intended to function as a flow‑through shelter and does not require full climate control or enclosure. The sides of the shelter will remain open, and roll‑up doors are not required. Accordingly, the humidity control language in Paragraph 2.b of the SOW is not intended to require the contractor to achieve controlled interior humidity levels within an open‑sided shelter. The contractor is not required to provide dedicated humidity control systems for this site under the current concept. | ||
| Paragraph 2.c in SoW also calls for fire detection and life safety systems. Will a simple local fire detection system conneted to fire alarm horns and strobes suffice this requirement? | The fire detection and life safety systems must be designed, installed, and integrated in strict accordance with Unified Facilities Criteria (UFC) 3-600-01 (Fire Protection Engineering for Facilities), NFPA 72 (National Fire Alarm and Signaling Code), DoD/DoW safety standards, and and Host Nation (Government of Japan) Laws. | ||
| Misawa Site C-1 | Are the specified 10 m by 15 m dimensions required to be clear usable interior dimensions, or are they the overall exterior dimensions of each structure? | The Government confirms that the 10 m × 15 m dimensions are required to be clear, usable interior dimensions of each shelter. These measurements are not overall exterior dimensions; they represent the minimum unobstructed interior footprint the structures must provide. Contractors may size the exterior envelope as needed to achieve the required clear interior space, provided all functional requirements are met and any layout adjustments are submitted for Government review and approval. | |
| Can the Government confirm that the minimum 9 m height is the required eave height rather than the peak roof height or minimum vehicle clearance? | The contractor can submit proposals for a membrane structure with a minimum eave height of 7.0 meters, which will be subject to the technical and regulatory evaluations by the Government. | ||
| The shelter shall have opening on each short end of the building. What size should the opening be? | The structure shall be configured as a permanent open-ended flow-through (no doors) with clear-span openings of W 6.0 m X H 5.0 m centered. |
Contractor/manufacturer must design the steel framing, membrane tensioning, and concrete foundations to withstand Japanese typhoon wind loads specifically calculated for an open-ended building envelope with internal wind uplift pressure.
| Paragraph 15.m in SoW calls for wall and roof insulation. Is this mandatory if the shelter will be opened from 2 sides? | The Government confirms that the requirement in Paragraph 15.m for wall and roof insulation is not mandatory for this site. This shelter is designed as a flow‑through structure, with two sides remaining open, and therefore does not require climate control or insulation under the current concept. Insulation is not required unless future Government direction changes the operational intent of the shelter. | |
| Misawa Site C-1 | The SOW requires the most stringent wind, snow, and seismic loads required anywhere in Japan regardless of project location. Does this mean nationwide maximum values, or the code-required design values applicable specifically to Misawa Air Base? | The Government confirms that all structural loading requirements—wind, snow, and seismic—shall be based on the code‑required design values specific to Misawa Air Base. The intent is not to apply nationwide maximums, but rather the appropriate Misawa AB design criteria as established by local codes and UFC guidance. |
| The SOW requires compliance with the Misawa AB Installation Facilities Standards, while Sheet G-101 references NAF Atsugi architectural standards and colors. Which standard governs, and can the current Misawa standards and approved color schedule be provided? | The Government confirms that this project is governed by the Misawa Air Base Installation Facilities Standards. Any reference to NAF Atsugi architectural standards or color requirements was included in error and does not apply. The Government will provide the current Misawa AB standards and approved color schedule to ensure the contractor designs in accordance with the correct installation requirements. | |
| What minimum fire classification, flame-spread rating, UV resistance, expected service life, and manufacturer warranty are required for the membrane material? | Fire Classification & Flame-Spread Rating shall conform with the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) standards. At minimum, Type B Membranes (PVC-coated glass fiber): Typically certified as Quasi-noncombustible or Fire-retardant shall be used. For UV protection, PVC (Types B & C) requiring PVDF (Polyvinylidene Fluoride) or TiO₂ (Titanium Dioxide) protective top coat to block UV rays, preventing plasticizer migration, and providing a self-cleaning surface shall be be used at the minimum. Service life should be for 20 years minimum with a minimum of 10-years warranty period. | |
| What corrosion-protection system is required for the structural steel, connections, fasteners, and exposed metal components? | The Contractor shall ensure all structural steel frameworks, tension cables, and connection hardware are corrosion-protected in strict accordance with the Japanese Building Standard Law (BSL) and applicable Japanese Industrial Standards (specifically JIS H 8641, JIS G 3549, and JIS B 1186). The Contractor will need to consult with their design team/engineer of record to determine and finalize the exact galvanizing classes, coating thicknesses, and material specifications required to safely withstand the site's specific environmental corrosivity and structural tension loads over the structure's intended design life. | |
| Misawa Site C-1 | Would a complete reinforced concrete slab beneath each membrane structure be acceptable as an alternative to concrete footings with an asphalt interior surface? | Scope requires concrete foundation with a standard slab on grade for flatwork to be a minimum of 200mm (8”) of 34,475 kPA (5000-psi), concrete with reinforced steel pad. The scope also requires the Geotechnical Report should be prepared and provided in accordance with UFC 3-220-01 at a minimum and provide requirements and recommendations for all new foundations along with roadway pavement design requirements. |
| Must the membrane structures and foundation bearing surfaces be completely level while the surrounding asphalt is graded for drainage? If so, will concrete or asphalt transitions be required at the entrances and exits? | Note that this is a Design-Build contract. Contractor’s Design Team shall fully coordinate this with their structural and other engineering disciplines. The Designer of Record (DOR) must ensure that all membrane structure column bearing surfaces and interior floor slabs are designed strictly level, while the surrounding exterior site plan is designed with positive grading to shed water away from the structure. The DB Contractor’s design must establish a Finished Floor Elevation (FFE) for the interior concrete slab and structural footings that is sufficiently elevated above the highest adjacent exterior grade. The design must guarantee no stormwater ingress into the structure or pooling at the structural column bases. The DB Contractor shall design and detail durable, load-bearing transition zones (e.g., reinforced concrete aprons) at all operational entrances and exits. These transitions must smoothly accommodate the elevation difference between the level interior slab and the sloped exterior asphalt, engineered to withstand the project's specified vehicle and forklift traffic without edge failure or rutting. | |
| Sheet G-101 specifies 4,000 psi concrete, while the SOW requires 5,000 psi concrete for flatwork. Can the Government confirm which concrete strength governs for foundations, slabs, and AST pads? | SOW governs in this case and the concrete shall be 5,000 psi. | |
| Are the structure locations, the indicated 8 m separation, and the offsets from the structures to the site boundaries mandatory minimum clearances? | The Government confirms that the structure locations, the indicated 8‑meter separation, and the offsets from the structures to the site boundaries are mandatory minimum clearances. These distances must be maintained in the final design unless a formally submitted deviation is reviewed and approved by the Government. | |
| Misawa Site C-1 | The SOW requires a two-way ingress/egress drive, while the drawings indicate three connections to existing roads. Are all three access points required, and does the 4,200 SM paved staging area satisfy the requirement for a new paved access road? | The Government confirms that all three access points shown in the drawings are required to support two‑way ingress/egress and overall site circulation. The contractor may propose alternative access configurations, and the Government will take any such recommendations under advisement, provided all functional and safety requirements are maintained. |
| Sheet C-400 shows 100 mm of asphalt over 250 mm of aggregate base, while the SOW requires 100 mm of asphalt over 150 mm of aggregate base and 150 mm of aggregate subbase. Which pavement section shall be used for pricing? | SOW governs in this case and following requirement shall be used: Any new pavement for the vehicular parking areas or roadways shall be a minimum of 100 mm or 4-inches of flexible hot mix asphalt (2-inch surface course and 2-inch intermediate course) on 150mm or 6-inches of graded-crushed aggregate base course on 150 mm or 6-inches aggregate subbase for flexible pavements on compacted subgrade. | |
| Since the whole drainange system falls under contractors responisbilty can we propose of installing infiltration system / industrial soakaway on the same site? | Design-Build (DB) Contractor can propose the infiltration system/industrial soakaway which will be subject to technical reviews and approval. The proposed system must be comprehensively sized and engineered to manage peak storm events (including regional typhoon rainfall intensities) without causing any localized flooding, on-site ponding, or water backing up onto the exterior asphalt or interior concrete slab. The design must ensure that the infiltration system does not supersaturate the subgrade, destabilize the structural foundations of the membrane structures, or cause frost heave beneath paved surfaces. | |
| Is contractor required to design oil-water separation systems required around 10K Gal Tank? | Oil-water separator for this project is not required; however, SOW requires to Design the spill containment system in accordance with UFC 1-200-01, federal, state, and local regulations. | |
| Misawa Site C-1 | Will tree clearing be permitted along the northern and western site boundaries, and can the Government identify the required clearing limits and landscaping-restoration requirements? | The SOW doesn't requires removal of any trees and removal of trees are strictly prohibited without approval. If the Design-Build Contractor determines that localized tree clearing is absolutely necessary to accommodate their final design, utility routing, or structural clearances, the Contractor must submit a formal Tree Removal and Mitigation Request for review. Any proposed clearing remains subject to the sole discretion and formal approval of the 35th Civil Engineer Squadron (35 CES). If approved, the Contractor shall be responsible for all associated surveying, permitting, and executing the required landscaping restoration/reforestation in strict compliance with 35 CES environmental standards. |
| The SOW refers to primary and secondary ASTs, while Sheet C-301 shows only one 10,000-gallon tank. How many Government-furnished ASTs must the concrete pad accommodate? Will this be one piece AST with 2 sections (Primary and Secondary)? | The project shall include a reinforced concrete pad for a single 4,000-gallon Aboveground Storage Tank (AST) within a 5.0m × 12.0m footprint. This pad shall serve as the secondary spill containment basin, with a finished wall height engineered by the Contractor to provide complete volumetric containment (110% of tank capacity plus equipment displacement and rainfall freeboard), while maintaining a safe, low-profile height for operator egress. AST’s will be furnished by the government and will not be part of the scope of this project.This language will be revised in the next version of SOW. | |
| The SOW identifies an AST envelope approximately 3 m in diameter and 10 m long, which appears larger than the 10,000-gallon tank shown on the drawing. Can the Government provide the exact capacity, dimensions, operating weight, and configuration of AST? | The project shall include a reinforced concrete pad for a single 4,000-gallon Aboveground Storage Tank (AST) within a 5.0m × 12.0m footprint. This pad shall serve as the secondary spill containment basin, with a finished wall height engineered by the Contractor to provide complete volumetric containment (110% of tank capacity plus equipment displacement and rainfall freeboard), while maintaining a safe, low-profile height for operator egress. This language will be revised in the next version of SOW. | |
| When will tank shop drawings, saddle reactions, anchor locations, nozzle locations, and other design data be provided? Will the Government deliver and set the tanks, or must the Contractor unload and install them? | The SOW states AST’s will be furnished by the government and will not be part of the scope of this project. | |
| Misawa Site C-1 | Is the Contractor responsible for tank anchorage, grounding and bonding, fuel piping, valves, electrical connections, monitoring equipment, or protective bollards? | No. The SOW states AST’s will be furnished by the government and will not be part of the scope of this project. |
| No remote spill-containment system is shown on the conceptual drawings. Can the Government identify the preferred location and confirm whether an open basin, underground tank, or another containment method is acceptable? | The project shall include a reinforced concrete pad for a single 4,000-gallon Aboveground Storage Tank (AST) within a 5.0m × 12.0m footprint. This pad shall serve as the secondary spill containment basin, with a finished wall height engineered by the Contractor to provide complete volumetric containment (110% of tank capacity plus equipment displacement and rainfall freeboard), while maintaining a safe, low-profile height for operator egress. This language will be revised in the next version of SOW. | |
| What is the capacity of the largest refueler expected at the site, and which portion of the staging area shall be treated as the refueler parking and spill-containment area? | The Government confirms that the largest refueler expected at the site is the R‑11 aircraft refueler, which has a 6,000‑gallon capacity and represents the design basis vehicle for all staging, maneuvering, and spill‑containment considerations. |
R-11 refuelers will utilize the site for short-term operations and will not be parked for long-term. When necessary for vehicle servicing or maintenance, R-11s will position adjacent to the Aboveground Storage Tanks (ASTs) to discharge fuel into the dedicated 4,000-gallon product recovery tank. All refuelers and support vehicular traffic will transition through designated flow-through structures to conduct scheduled preventive maintenance. Refer to the above comment responses on spill-containment system.The Contractor is permitted to propose modifications to the physical locations of the flow-through structures and the Aboveground Storage Tank (AST) secondary containment system within the proposed site layout. Any such adjustments are subject to formal review and written approval by the Government prior to the initiation.
The Contractor must submit a revised Site Layout Plan demonstrating that the relocated structures:
Maintain optimal operational traffic flow for R-11 refuelers and support vehicles.
Comply fully with all applicable Unified Facilities Criteria (UFC), environmental regulations, and SPCC secondary containment capacity requirements.
Do not interfere with existing utility corridors or secure perimeter setbacks.
| Can the Government clarify the requirement that at least 25 percent of the required containment volume must reach the remote system before shared containment begins to pond at the parking area? How shall normal rainwater be discharged, and is an oil-water separator required? | The project shall include a reinforced concrete pad for a single 4,000-gallon Aboveground Storage Tank (AST) within a 5.0m × 12.0m footprint. This pad shall serve as the secondary spill containment basin, with a finished wall height engineered by the Contractor to provide complete volumetric containment (110% of tank capacity plus equipment displacement and rainfall freeboard), while maintaining a safe, low-profile height for operator egress. This language will be revised in the next version of SOW. To facilitate the discharge of accumulated stormwater, the Contractor shall install a manually operated, normally closed, lockable isolation valve on the AST secondary containment basin. This valve shall enable the controlled release of retained rainwater to surface grade or the designated site drainage system, contingent upon prior visual inspection confirming the absence of hydrocarbon sheen or contamination. An oil-water separator is not part of this SOW. | |
| Misawa Site C-1 | Is the Contractor responsible for locating, disconnecting, removing, and capping all electrical, water, sewer, communication, or other services connected to the abandoned building? | The Government confirms that the Contractor is responsible for locating, disconnecting, removing, and properly capping all electrical, water, sewer, communication, and any other utility services connected to the abandoned building. This responsibility includes verifying all existing service connections, coordinating any required outages, and ensuring all work is completed safely and in accordance with applicable codes and base standards. |
| Can the Government confirm the dimensions, construction type, and complete demolition limits of the abandoned building, including its slab, foundations, underground structures, and surrounding pavement? | The existing building demolition is no longer required and the note on drawing sheet C-200 will be revised. The Contractor is permitted to propose modifications to the physical locations of the flow-through structures and the Aboveground Storage Tank (AST) secondary containment system within the proposed site layout to avoid this building demolition. Any such adjustments are subject to formal review and written approval by the Government prior to the initiation. |
The Contractor must submit a revised Site Layout Plan demonstrating that the relocated structures:
Maintain optimal operational traffic flow for R-11 refuelers and support vehicles.
Comply fully with all applicable Unified Facilities Criteria (UFC), environmental regulations, and SPCC secondary containment capacity requirements.
Do not interfere with existing utility corridors or secure perimeter setbacks.
| If asbestos, lead-based paint, contaminated soil, or unidentified hazardous materials are discovered, will the resulting testing, remediation, disposal, and schedule impacts be handled as a contract change? | A situation such as this would result in "unforseen site conditions" and would require a modification to the contract. The government would request a proposal from the company to account for any additional work, when needed. | |
| Can the Government identify the exact sanitary sewer manhole that must be relocated and mark the existing upstream and downstream sewer alignment during the site visit? | Existing underground utilities including but not limited to pipes, cables, and duct lines are shown on the contract drawings for informational purposes only. This utility data was compiled from the best available historical records; however, the Government does not guarantee the accuracy, completeness, or routing of these subsurface lines, nor does it verify the connections shown. The Contractor shall bear sole responsibility for identifying, verifying, and locating all active and abandoned underground utilities prior to commencing any excavation or site-disturbance activities. To ensure site safety and prevent operational disruptions, the Contractor must: Conduct physical utility locating (including non-destructive methods such as ground-penetrating radar, electromagnetic locating, or potholing) to confirm the exact location, depth, and alignment of all subsurface assets.Clearly mark verified utility corridors in the field and implement comprehensive protection measures to prevent damage during construction.Coordinate with 35th CES and local utility locators to obtain all necessary dig permits. | |
| Misawa Site C-1 | Can the Government provide the existing pipe diameter, material, invert elevations, flow direction, approximate flow rate, and available inspection records for this sewer system? | The Government does not possess certified or verified engineering records detailing the specific pipe diameter, material, invert elevations, flow direction, flow rates, or historical inspection records for the active sewer system within the project boundaries. As outlined in the contract documents, all subsurface utility data provided on the drawings is strictly for informational purposes, compiled from historical records, and is unverified. |
Per the contract requirements, the Contractor is solely responsible for determining the exact physical properties and locations of existing underground utilities necessary to complete the work. The Contractor shall perform all required field verification, utility locating, and non-destructive site investigations (e.g., potholing, CCTV inspection) at their own expense prior to commencing work.
Can the Government identify the intended primary electrical connection point and confirm whether the transformer shown near the southwest side of Sheet C-100 is the anticipated source? Can we Government provide the informations on the trasformer and Is it possible that the transformer is already overloaded? 1. The designated primary electrical point of connection is estimated to be located across the road near the ADR warehouse. The Contractor must obtain formal approval from the 35th CES through the Project Manager prior to making this connection. Alternatively, the Contractor is permitted to investigate and propose other viable electrical connection sources, subject to the same 35th CES approval process. Under this Design-Build contract, the Contractor is solely responsible for field-verifying existing conditions, performing all necessary engineering calculations, and appropriately sizing the available primary voltage, phase, frequency, and overall capacity required to safely support the connection.
2. The 100 KVA capacity specified in the SOW is the maximum design limit for the transformer and represents the upper boundary of the project scope; the Government anticipates that the actual operational load calculated by the Designer of Record will be below this capacity. The Contractor shall utilize the 100 KVA limit as the design baseline for the base bid. Any design optimization or sizing adjustments below this maximum threshold, as determined by the Contractor's final electrical load calculations, is considered standard design-build development and will not be treated as a change in contract scope or justify any equitable adjustments.
3. The transformer location is to be planned and proposed by the Design-Build Contractor, subject to final Government/35th CES approval.
4. It is the Contractor’s responsibility to conduct any necessary site investigations, utility tracing, and capacity studies to obtain existing single-line diagrams, electrical utility plans, and load data. All design work based on these findings is subject to final Government approval.
What minimum interior task-lighting and exterior-lighting levels are required? If wall-mounted fixtures cannot provide compliant coverage of the full staging area, will site-lighting poles be permitted? Lighting levels and installation shall comply with UFC 3-520-01 Interior/Exterior Electrical Systems, and UFC 3-530-01 Interior and Exterior Lighting Systems and Controls. Under UFC 3-530-01 (Interior and Exterior Lighting and Controls), exterior industrial and vehicle areas are categorized by their risk and activity levels. The minimum illuminance targets are:
Interior: A minimum of 30 foot-candles (fc) at work-surface height is required to safely conduct preventive maintenance.
Exterior: A minimum of 2 foot-candles (fc) is required across the active staging area for safe vehicle maneuvering and security.
Contractor shall verify these requirements within the referenced UFCs.
Yes, site-lighting poles are permitted and expected.
| What communication systems are required in each structure, including data outlets, telephone, fiber, radio, or empty communication pathways? | None, these are flow through structures. | |
| Misawa Site C-1 | The SOW also refers to utilities being installed later; what utilites are expected to not be in place in time of completion of the facility? | Didn't find the reference to "later" in SOW. Note that SOW states, "If utilities are not in place prior to the completion of the facility, contractor will have to come back once main utilities are constructed to run services and make tie-ins."The Project includes underground utilities (primary and secondary electrical distribution), relocation of the sewer manhole that is currently located in the center of the project work site, paving/flatwork, storm drainage, and fencing. |
| What permanent fence type, height, mesh, coating, anti-climb features, post spacing, and foundation requirements shall be provided? | The Contractor shall install a 6-foot (1.8-meter) high, heavy-duty industrial chain-link fence utilizing 9-gauge steel wire with a 2-inch (50 mm) mesh. To withstand Misawa's corrosive, high-snow environment, all fabric and components must be hot-dip galvanized (Class 2) or aluminized steel. In strict compliance with UFC 4-022-03, a top tension wire shall be used instead of a top rail to eliminate climbing handholds. Line posts must be set in concrete footings spaced at a maximum of 10 feet (3.0 meters) on center and embedded below the local frost line (minimum 24 to 36 inches / 600mm to 900mm depth), supported by structural calculations that account for local wind and snow loads. | |
| the SOW requires two 9 m swing gates and one motorized gate with an 18 m minimum opening. From where shall the one motorized gate be operated from? Will the other two swing gates be manualy operated? | The contractor shall install two manually operated 9-meter swing gates, positioned on the east and west sides of the facility, in lieu of the previously required 18-meter motorized gate, which is hereby removed from the scope of work. To ensure compliance with local traffic regulations and safe vehicle turn-radius standards, the Contractor is permitted to propose minor physical adjustments to the locations of the flow-through structures and the Aboveground Storage Tank (AST) secondary containment system within the proposed site layout. However, any such modifications must be formally submitted to the Government for review, and no physical installation or site adjustments related to these systems shall initiate prior to receiving formal, written Government approval. | |
| What type of 18 m motorized gate is preferred: sliding, cantilever, bi-folding, telescopic, or swinging? What access controls, safety loops, photocells, warning devices, and security interfaces are required? | The contractor shall install two manually operated 9-meter swing gates, positioned on the east and west sides of the facility, in lieu of the previously required 18-meter motorized gate, which is hereby removed from the scope of work. | |
| Misawa Site C-1 | Must the gate operators include battery backup, manual emergency operation, heaters, or other low-temperature and snow-protection features? | The contractor shall install two manually operated 9-meter swing gates, positioned on the east and west sides of the facility, in lieu of the previously required 18-meter motorized gate, which is hereby removed from the scope of work. |
| Will a laydown area, temporary office area, worker parking, haul route, and temporary construction utilities be available on or near Site C-1? | The Contractor’s Design-Build (DB) team shall actively coordinate with the Government Project Manager (PM) to collaboratively develop a Temporary Construction Site Plan. This joint coordination effort must detail all proposed laydown, temporary office, worker parking, and haul route locations, alongside layout drawings for temporary construction utilities. Once the plan is mutually developed, the Government PM will coordinate the internal review and obtain formal site approval from the 35th Civil Engineer Squadron (35 CES). The Contractor shall not utilize any base real estate or establish utility connections until written approval is issued by the Government | |
| The schedule requires the geotechnical investigation and topographic survey within 21 days after award. Will access, utility clearances, digging permits, and survey control be available early enough to meet this requirement? | The Government confirms that access, digging permits, utility clearances, and survey control will be coordinated early through RPT‑J and the 35th CES to support the requirement for completing the geotechnical investigation and topographic survey within 21 days after award. All base access and permitting actions will be processed immediately upon contract award to ensure the contractor can meet the mandated timeline. 35 CES utility clearances and digging permits will be coordinated through a form AF103 and would take 15-20 days for coordination. | |
| Are any existing geotechnical reports, pavement investigations, groundwater information, or nearby boring logs available for preliminary pricing? | There are no boring, groundwater data, or other historical documents available for these sites. | |
| Misawa Site C-1 | Can the Government clarify how the 90-day design period relates to the schedule showing the 65 percent design due 90 days after the pre-design meeting and the 100 percent design due 21 days after approval of the revised 65 percent package? | The Period of Design was updated to 120 days and Performance Period of Construction was updated to 180 days. 90 days for 65% design plus 21 days after this for the 100% design fits well within the 120 days design period for performance. |
| Can the Government confirm that the 150-day construction period begins with the initial authorization after Part I approval and therefore includes completion of the 100 percent design, Government review, and authorization of the remaining work? | Performance Period of Construction was updated to 180 days. Authorization to Commence Construction (All remaining project elements required outside the initial work elements): Within 1 day after the Revised 100% Design Package – Part 1 is approved by the Government | |
| Can procurement of long-lead membrane structures, structural steel, the transformer, fire-alarm equipment, and motorized gates begin immediately after award through separate early-procurement submittals? | The Government will allow separate, early-procurement submittals for long-lead items (specifically the membrane structures, structural steel, transformer, fire-alarm equipment, and motorized gates) immediately after award. However, all early procurement is conducted at the Contractor's sole financial and schedule risk. Any subsequent changes to the approved 100% design that impact these procured items shall be corrected at the Contractor's expense, with no adjustment to the contract price or performance period. | |
| May the Contractor submit separate design packages for demolition, utilities, pavement, foundations, structural framing, and other work to support fast-track construction? | The Government denies the request to submit separate, phased design packages. Per the SOW, the project is strictly structured around one comprehensive 65% design review and one final 100% design review. | |
| If main utilities or Government-furnished AST information are unavailable when required, will the completion schedule be extended for the resulting delay? | The SOW states AST’s will be furnished by the government and will NOT be part of the scope of this project. This should not lead to any delays to completion schedule. Refer to earlier comment responses on what is required for this (spill containment system). |
For any government delays, the contractor may request an extension and request for equitable adjustment where necessary.
| Misawa Site A-1 | The SOW identifies the project as QKKA26-1109, “Construct RBCP Storage,” while the drawings identify it as QKKA26-XXXX, “Construct Emergency PWM Storage.” Will corrected drawings be issued with the correct project number and title? | The Government confirms that the correct project identification for all design, construction, and contract documentation is: QKKA26‑1109 – CONSTRUCT EMERGENCY PWM STORAGE (SITE A‑1) The project number and title shown on the current drawing set (“QKKA26‑XXXX – Construct Emergency PWM Storage”) are outdated placeholders. |
| General Note 5 on Sheet G-101 instructs the Contractor to notify NAF Atsugi if artifacts or human remains are discovered. Can the Government confirm that this should refer to Misawa Air Base? | The Government confirms that the correct installation reference is Misawa Air Base. Corrected drawings will be issued to replace the note with the proper instruction: “Notify Misawa Air Base.” | |
| Can the Government provide the conceptual drawings in native AutoCAD/Civil 3D format, including the existing and proposed surfaces, alignments, profiles, point files, utility information, and aerial imagery? | There are no boring logs, groundwater data, GIS layers, or other historical subsurface documents available for this site. The Government can provide AutoCAD files of the concept plans that were submitted for bid purposes. These represent the extent of available native design files for this project. | |
| Can all available as-built drawings, GIS information, utility maps, geotechnical information, and previous surveys for Site A-1 and the access road be provided before proposal submission? | Existing underground utilities including but not limited to pipes, cables, and duct lines are shown on the contract drawings for informational purposes only. This utility data was compiled from the best available historical records; however, the Government does not guarantee the accuracy, completeness, or routing of these subsurface lines, nor does it verify the connections shown. The Contractor shall bear sole responsibility for identifying, verifying, and locating all active and abandoned underground utilities prior to commencing any excavation or site-disturbance activities. To ensure site safety and prevent operational disruptions, the Contractor must: Conduct physical utility locating (including non-destructive methods such as ground-penetrating radar, electromagnetic locating, or potholing) to confirm the exact location, depth, and alignment of all subsurface assets.Clearly mark verified utility corridors in the field and implement comprehensive protection measures to prevent damage during construction.Coordinate with 35th CES and local utility locators to obtain all necessary dig permits. | |
| Are the locations and orientations of the four membrane structures, access road, paved areas, fencing, gates, transformer, and underground utilities fixed, or may they be adjusted during design to improve constructability, drainage, and vehicle access? | The Government confirms that the locations and orientations of the four membrane structures, access road, paved areas, fencing, gates, transformer, and underground utilities may be adjusted during design to improve constructability, drainage, and vehicle access. Any proposed adjustments must be submitted to the Government for review and approval prior to incorporation into the final design. | |
| Can the Government confirm the number, dimensions, thicknesses, reinforcement, foundation depths, and condition of the existing concrete pads at Site A-1? | The existing concrete pads are approximately 10 meters x 5 meters each. There are 24 concrete pads within the project limits as shown on the drawing plans. Note that the Contractors were provided the opportunity of the site visit for assessing the conditions and taking measurements in the field. | |
| Are any records or drawings available showing what the existing pads previously supported and whether foundations, piles, utilities, grounding systems, or buried structures remain beneath them? | No records are available. | |
| Misawa Site A-1 | Must all existing concrete pads be completely removed, including foundations and reinforcing steel, or may portions outside the new foundations and utility trenches remain? | The Contractor may submit a design proposal to salvage and utilize the existing concrete pads if doing so aligns with the final design intent and meets all structural, load-bearing, and utility requirements of the contract. Any such proposal must demonstrate that utilizing the existing pads results in a project cost savings to the Government while maintaining full design integrity. If the existing pads do not meet the final design requirements or cannot be structurally validated by the Contractor’s design team, they must be completely removed, including all foundations and reinforcing steel. |
| Would the Government permit the existing concrete pads to remain in place and the entire A-1 site to be raised above them with engineered fill, provided the approach is supported by the geotechnical report and approved by the Designer of Record? Under this approach, may suitable, uncontaminated excavated soil from the C-1 site be transported to A-1 and reused as structural fill, subject to testing, compaction requirements, and Government approval? | The proposed approach of leaving the existing concrete pads in place at the A-1 site, raising the site with engineered fill, and utilizing suitable, uncontaminated excavated soil from the C-1 site as structural fill must be fully designed, evaluated, and justified by the Contractor's Design-Build (D-B) team. The Government cannot provide pre-approval for this specific methodology without a comprehensive engineering evaluation. |
